OBJECTIVE To evaluate the extent sensory and motor blocks produced by the epidural injection of different volumes of 0.25% bupivacaine (Bu) with methylene blue (MB), in dogs. STUDY DESIGN Prospective experimental trial. ANIMALS Twenty healthy adult mongrel dogs, weighing 9.9 +/- 1.9 kg. METHODS Dogs were randomly allocated into one of four groups that(More)
OBJECTIVE To evaluate the potential of an intravenous (IV) sevoflurane formulation for maintenance of general anesthesia in dogs. STUDY DESIGN Prospective crossover design. ANIMALS Six healthy, mature, mixed-breed dogs, four males and two females, weighing 11.7 ± 3.4 kg. METHODS Anesthesia was induced and maintained with propofol IV for(More)
Background: Several pulmonary and hemodynamic complications may occur during mechanical ventilation of the lungs. The use of a positive end-expiratory pressure (PEEP) can improve oxygenation and prevent atelectasis, although this method can cause important hemodynamic side effects. Mostly, these hemodynamic effects are due to increased airway pressure that(More)
Background: The drugs that promote sedation, analgesia, and anesthesia, as inhalatory agents, phenothiazines, benzodiazepines, alpha-2 adrenergic agonists, and opioids, can promote different kinds of side effects. The concept of a balanced anesthesia in equine was developed in order to minimize adverse effects inherent to anesthesia, creating a combination(More)
Isoflurane is a halogenated ether which is used for general anesthesia. To stabilize a new formulation in order to evaluate the potential to reduce the dose required for general anesthesia, an isoflurane-loaded nanoemulsion was proposed. A high-pressure homogenization technique was used to develop drug-loaded nanoemulsions which presented droplet size of(More)
